Leaf- yellowing | The first step | 34-38 | 34-36 | 0.5-1 | 50-56 | 50-56 | Most of leaves at the upper tier yellow, but their stem is still green. |
Leaves at the upper tier get soft, and those at the lower tier emit heat. | Yellowing status: leaves at the lower tier or with higher moisture content yellow lightly; leaves at the middle and upper tier do the opposite. At the wet-bulb temperature, leaves with lower moisture content turn yellow heavily, and those with higher moisture content do the opposite. |
The second step | 40-42 | 36-38 | 0.5 | 25-30 | 75-86 | Leaves at the upper and second tier completely yellow, and those at the lower tier almost yellow. | All leaves and stems become soft. | Make sure that leaves completely yellow and are softened. Leaves at the upper tier and those with higher moisture almost yellow. | |
Color-setting | The third step | 46-48 | 36-38 | 0.3-0.5 | 20-25 | 95-111 | All leaves and their stems completely yellow. | Leaves at the upper tier roll up, and those at the lower tier roll a little. | All leaves completely yellow and roll up. Their stem yellow. The temperature is distributed evenly. |
The forth step | 52-54 | 38-40 | 0.5-0.8 | 20-24 | 115-135 | Turn the back of leaves yellow to reduce the color difference. | All leaves are rolled good except for their stem. | Extend the drying time to reduce the color difference and to facilitate leaves to roll up; and keep the temperature even. | |
Stem-drying | The fifth step | 60 | 41 | 1 | 12-14 | 127-149 | The stem is dried half. | Raise the temperature stably; Don't lower the temperature; and keep the same humanity. | |
The sixth step | 68 | 42 | 1 | 20-24 | 147-173 | The stem is dried up. | Never lower the temperature. Raise the temperature on a stable basis; don't reduce the temperature, or the water in the stem will seep; and don't increase the temperature and the humanity too highly, or the leaves will be dried red. |
